A simple protein-based surrogate neutralization assay for SARS-CoV-2	2020-10-02		.txt	text/plain	7576	380	53	Here, we present a safe and efficient protein-based assay for the detection of serum and plasma antibodies that block the interaction of the SARS-CoV-2 spike protein receptor binding domain (RBD) with its receptor, angiotensin-converting enzyme 2 (ACE2). Here, we present a safe and efficient protein-based assay for the detection of serum and plasma antibodies that block the interaction of the SARS-CoV-2 spike protein receptor binding domain (RBD) with its receptor, angiotensin-converting enzyme 2 (ACE2). SARS-CoV-2 ELISAs are performed by immobilizing a recombinantly produced viral antigen (such as the spike trimer or RBD) ( Figure 1B and Supplemental Figures 1 and 2; supplemental material available online with this article; https://doi.org/10.1172/jci.insight.142362DS1) (see Methods) onto multiwell plastic plates that are then incubated with diluted patient serum or plasma samples.	./cache/cord-280939-d478p8u6.txt	./txt/cord-280939-d478p8u6.txt
